A lid (10) for a well plate (2) is provided. Pins (14) penetrate the lid (10) and project downwardly into the wells (6) of the well plate (2). Thermal energy is applied to the upper end of the pins (14) to regulate the temperature of liquid samples (4) in the well plate (2). Ultrasonic energy may be applied via, for example, an ultrasonic horn (36), in order to sonicate the liquid samples (4). Alternately, an electrical charge may be applied to the upper ends of the pins (4) via an electrical charge device (48) to attract any charged materials, such as DNA, in the liquid samples (4) and to selectively segregate the charged materials from the liquid sample (4). |
